80 + 150 - 45= 185 (take away 45 as that was duplicated in the groups)
185/500= 0.37
Answer:
From the given graph:
the coordinates of triangle RST are;
R= (2, 1),
S= (2,-2),
T= (-1,-2)
Given: Scale factor =
and center of dilation at (2,2)
The mapping rule for the dilation applied to the triangle as shown below:
; where k represents the scale factor i.e,
or we can write it as ;
For R=(2, 1)
The image R' = 
⇒ R'=
Similarly for S= (2, -2) and T= (-1,-2)
therefore, the image of S'= 
⇒ S'=
The image of T' =
⇒T' = 
Now, labelling the image of triangle R'S'T' as shown in the figure given below
Answer:
Step-by-step explanation:
p(headache) = 0.45
p(headache | taking a vitamin) = 0.15/0.50 = 0.30
The two probabilities <em>are not equal</em>.
